Operator GuideWallet Infrastructure
Gas Sponsorship
Dashboard → Wallet Infrastructure → Gas Sponsorship
Controls which transactions your app sponsors and the limits applied per user. All rules are enforced server-side by the Pollar Server — they cannot be bypassed from the client SDK.
Sponsored transaction types
Select which Stellar operation types are covered by your gas wallet:
| Type | Description |
|---|---|
payment | Asset transfers between wallets |
trustline | Adding a new asset trustline to a wallet |
activation | Account sponsorship sequence for new wallets |
| Custom | Define rules based on asset, amount range, or other criteria |
Transactions of unselected types are rejected before reaching the Stellar network.
Per-user limits
Prevent abuse by setting caps per user:
| Setting | Description |
|---|---|
daily_ops_cap | Maximum sponsored operations per user per day |
max_fee_per_tx | Maximum fee the gas wallet will pay per transaction (in stroops) |
approved_assets | Whitelist of assets eligible for fee sponsorship |
Custom rules coming soon
Define granular sponsorship rules — for example, only sponsor USDC payments under $100, or only sponsor trustlines for configured assets.
